OpenStack Cloud OpenStack is a community of open sourcedevelopers, participating organizations and userswho are building and running the open source cloudoperating system. “OpenStack is an Infrastructure as a service which is knownas a Cloud Operating System, that takes resources such ascompute, storage, network, virtualization technologies andcontrols those resources at a data center level” “OpenStack’s basic requirement: “Cloud must be simpleto implement and massively scalable”

Why OpenStack•Control and Flexibility. Open source platform means you’re never lockedto a proprietary vendor, and modular design can integrate with legacy orthird-party technologies to meet your business needs.•Industry Standard. More than 60 leading companies from over a dozencountries are participating in OpenStack, including Cisco, Citrix, Dell, Inteland Microsoft, and new OpenStack clouds are coming online across theglobe.•Proven Software. Run the same software that today powers some of thelargest public and private clouds in the world.•Compatible and Connected. Compatibility with public OpenStack cloudsmeans enterprises are prepared for the future—making it easy to migratedata and applications to public clouds when conditions are right—based onsecurity policies, economics, and other key business criteria.
